Sounds like that DP might have a different Port number or even an IP address that doesn't match up with the server. Make sure the Port number is the same as the server console. Typically this is 6600, but if someone changed that DP2K, it might need to be switched back. Also, are you running DHCP on the server? This is pretty typical too, however many programmers set their own IP addresses. Check the IP address on that DP2K. Depending on how your console is set up, you may need to enter a new IP address or enable DHCP.
